I don't cut my scraps to a particular size until I need them. I consider a scrap anything bigger than 3/4" square and less than 1/8 yd. Less than 1/8 yd pieces are sorted by color in the small Sterilite drawers. 1/8 to 1/2 yd pieces are folded and stored in the medium size Sterilite drawers. Anything over 1/2 yd is ruler folded and stored on a shelf like a book. There are always a few exceptions to this, but in general I find this works pretty well for me. I've been through several sorting variations and I'm sure I'll change again when this one no longer works for me. The only real constant in life is that things will change.
